Fastener for roller window shades



Patented Bday lg, 193@ earner FASTENER F01?) R-GLLR VNDOW SHADESApplication filed November 24, 1928.

This invention relates to a fastener' for roller window shades by whichto retain the shade in extended position.

ln its preferred embodiment this invention constitutes a devicepivotally secured upon a window sill and by means of which the rollershade may be held in extended position.

Prior to this invention no adequate means has been produced by which toretain a roller window shade in extended position and at the same timeretain said shade out of Contact with the window. This invention, asdisclosed in the following specification, provides a device which, whennot in use, is out of sight beneath the window sill and when in useholds the window shade in a position such that ventilation may beobtained without letting in an appreciable amount of light through thewindow opening.

The principal object of this invention is the provision of a device ofthis class by which to retain a roller window shade in extended andremoved position with relation to the window frame.

Another object of this invention is the provision of a device of thisclass which, when not in use, may be moved outof sight beneath thewindow sill to which it is attached.

Other and further advantages of this invention will appear from aconsideration of the following specification taken in connection withthe accompanying drawings, and in which:

Fig. 1 is a front elevation of a window and roller sash showing onemodification of this device in position of use;

Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1 andshows the extent to which the roller shade is removed from the windowsill;

Fig. 3 is an enlarged bottom plan view of the device shown in Figs. 1and 2;

Fig. l is a sectional .view taken on the line 4 4: of Fig. 3;

Fig. 5 is a bottom plan view of another modification of this invention;and

Fig. 6 is a sectional view taken on the line 6-6 of Fig. 5.

Referring to the drawing and particularly Serial No. 321,594.

wedge shaped opening 17 by which to receive the tassel or cord of theroller shade. From adjacent the pivotal end 1l the edge 19 of thisdevice is provided with a series of wedge shaped openings 21, the opensides of which extend toward the' end 16.

A. screw 22 constitutes the means by which the device is mounted uponthe under face of the window sill 23. When it is `desired to use thisdevicev it is swung outwardly from the position below the sill 23 to aposition substantially at'right angles to said sill. Inasmuch as thepivotal point of the device is centrally located with relation to thesill, the outer end 16 will, when moved into position of use7 besubstantially in line with the Center of the window. The roller shademay now be drawn downwardly' and the cord or tassel thereof snapped intothe outermost opening 17 or any ofthe openings 2l, depending entirelyupon the angle at which the operator desires the shade to be located.

The shade securedto the fastener is somewhat out of vertical alignmentwith the window and as a result ample ventilation may be obtained aroundthe lowermost end of the shade but little or no light will enter theroom.

Referring now to Figs. 5 and 6 a slight modihcation of this invention isshown. In this instance the device l() is of consider ably greaterlength than in the previous modification and is therefore provided witha downwardly extending flange 25 on both longitudinal walls. A wedgeshaped opening 26, located in the outer end 2T, provides means forsecuring the cord or tassel of the roller shade. This device is mountedin a manner similar to that shown above being pivotally secured to theunder face of the window sill by means of the screw 22.

Both modifications of this invention are of such dimensions that whenmoved to potition of rest they are wholly concealed by the overhang ofthe window sill and when in position of use are substantially centeredwith respect to the Window whereby to facilitate the securing of theroller shade thereto.

While only two modifications of this invention have been shown anddescribed, applicant does not int-end to be limited thereto since it isobvious that other modifications or adaptations may be made withoutdeparting from the spirit and scope of this invention as set forth inthe following claims.

Having thus set forth my invention what I claim is new and for which Idesire protection by Letters Patentis 1. A fastener for roller windowshades comprising a pivotally mounted member having a plurality ofspaced wedge shaped openings by which to receive and retain the cord ofsaid shade.

2. A fastener for roller window shades comprising an elongated memberpivotally mounted upon the under face of a window sill, a plurality ofwedge shaped openings formed in one longitudinal wall of said fastenerand an angle fiange defining the other longitudinal wall of saidfastener.

3. A fastener for roller window shades comprising a metal strip, aflange forming one longitudinal edge to said strip, walls in the otheredge of said strip, defining tapered openings, said openings beingspaced apart to facilitate securing said shade at various angles to awindow upon which it is mounted.

4. A fastener for roller window shades comprising ametal strip, a fiangeforming one longitudinal edge to said strip, walls defining a pivotopening in one edge of said strip, walls defining a wedge shaped openingin the other edge of said strip and means, in the edge of said stripopposite said flange, adapted to engage the cord of said shade to permitsecuring said shade at various angles to a window upon which it ismounted.

In testimony whereof I have affixed my signature.
